Impact of Timing of Minor Amputations After Revascularization on Patient Outcomes.

Background: Vascular complications from diabetes contribute significantly to major and minor limb amputations. Diabetes is a major health burden in Saudi Arabia, with increased incidence in rural areas. The purpose of this study was to evaluate the timing of minor lower limb amputations after revascularization and their relative outcomes.

Double Iatrogenic Esophageal and Duodenal Injury Induced by Endoscopic Retrograde Cholangiopancreatography: A Case Report.

Endoscopic retrograde cholangiopancreatography (ERCP) is a frequently performed procedure in the management of hepatobiliary diseases that can be conducted as a therapeutic or diagnostic procedure. Also, it can be done with or without sphincterotomy and stent insertion. Hemorrhage is one of the most common post-ERCP complications, which can be presented as late as 10 days.

An 8-Year-Old Boy With Hepatic Embryonal Sarcoma Managed With Surgical Resection.

The extent of hepatic tumors in childhood differs from that found in older age groups. Some of these tumors are believed to be quite rare like undifferentiated embryonal sarcoma of the liver (UESL). The challenge in diagnosis arises from the nonspecific clinical, biochemical, and radiological features, with definitive diagnosis requiring pathological confirmation following surgical excision.

A case report of spindle cell lipoma.

Spindle cell lipoma (SCL) is an uncommon benign tumor. A 67-year-old male with multiple comorbidities, presented with a complain of swelling in the neck, which was excised, and the diagnosis of spindle shape lipoma was made based on pathological examination.

A case report of retroperitoneal Ewing sarcoma requiring adrenalectomy.

Introduction And Importance: Ewing's sarcoma is a rare entity of malignant in both skeletal and extra-skeletal sites. There are few patients reported as Extra-Skeletal Sarcoma, and fewer reported cases for Extraskeletal Ewing sarcoma involving the retroperitoneal region. Reporting such a rare entity will add to literature in helping the diagnosis and management of such cases.

Buckling patterns in biaxially pre-stretched bilayer shells: wrinkles, creases, folds and fracture-like ridges.

We introduce a new experimental system to study the effects of pre-stretch on the buckling patterns that emerge from the biaxial compression of elastomeric bilayer shells. Upon fabrication of the samples, releasing the pre-stretch in the substrate through deflation places the outer film in a state of biaxial compression and yields a variety of buckling patterns. We systematically explore the parameter space by varying the pre-stretch of the substrate and the ratio between the stiffness of the substrate and film.

Nonsteroidal, antiinflammatory drug-induced gastrointestinal injuries and related adverse reactions: epidemiology, pathogenesis and management.

A large proportion of the population all over the world consumes acetylsalicylic acid (ASA: aspirin) or other nonsteroidal, antiinflammatory drugs (NSAIDs). This is associated with a considerable morbidity and mortality. Elderly patients, patients with prior history of peptic ulcer disease (PUD) or its complications, those who require high doses of NSAIDs and those undergoing concomitant therapy with corticosteroids or anticoagulants, are at particularly high risk of developing gastroduodenal injuries and related adverse reactions.

Objective: Knowledge of the pattern of gastrointestinal tract (GIT) disorders detected by endoscopy is important for clinicians. The objective of this paper is to report on the indications and yield of endoscopy.

Methods: Retrospective analysis of data of all patients below 18 years of age who underwent upper GIT endoscopy from 1414 H (1993 G) through to 1424 H (2002 G) over a 10-year period at King Khaled University Hospital, Riyadh, Kingdom of Saudi Arabia.

Biochemical and radiological predictors of malignant biliary strictures.

Aim: Differentiation of benign biliary strictures (BBS) from malignant biliary strictures (MBS) remains difficult despite improvement in imaging and endoscopic techniques. The aim of this study was to identify the clinical, biochemical and or radiological predictors of malignant biliary strictures.

Methods: We retrospectively reviewed all charts of patients who had biliary strictures (BS) on endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous cholangiography (PTC) in case of unsuccessful ERCP from March 1998 to August 2002.

Epidemiology and outcome of Crohn's disease in a teaching hospital in Riyadh.

Aim: To know the epidemiology and outcome of Crohn's disease at King Khalid University Hospital, Riyadh, Saudi Arabia and to compare the results from other world institutions.

Methods: A retrospective analysis of patients seen for 20 years (between 1983 and 2002). Individual case records were reviewed with regard to history, clinical, findings from colonoscopy, biopsies, small bowel enema, computerized tomography scan, treatment and outcome.

Malignant biliary strictures. Diagnosis and management.

Objective: To identify the cause, methods of diagnosis and management of malignant biliary strictures in our institution and compare with studies from other communities.

Methods: From March 1998 through to August 2002, we reviewed 1000 files of patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) at the Gastroenterology unit, King Khalid University Hospital in Riyadh, Kingdom of Saudi Arabia for malignant biliary strictures (MBS). Clinical, laboratory data, method of diagnosis and management were recorded.

Pattern of admission to hospitals during muslim pilgrimage (Hajj).

Objective: The pattern of medical conditions necessitating admission differs according to the weather condition in that particular year. Previous studies had been conducted during the hot weather, none over the last 10 years, were carried out during, the milder weather we are experiencing. The aim of this study is to establish the pattern of admission during this mild weather and to elucidate the possible risk factors.

Efficacy of hepatitis B vaccine in a cohortcommunity-based study in Riyadh and Hail regions of Saudi Arabia.

Background: Saudi Arabia used to be hyperendemic for HBV infection. Most of infection occurs in early life. HBV vaccine was, therefore, introduced in 1989 as the seventh primary immunogen of the EPI Program.

Tuberculous liver abscess: a case report and review of literature.

Tuberculous liver abscess is rare worldwide. We report a 45-year-old man who presented with abdominal pain, fever and weight loss. Ultrasound and computed tomography of the abdomen showed multiple cystic lesions in the liver.

This is a retrospective analysis of the medical records of 116 patients who presented to the gastroenterology division, department of medicine at King Khalid University Hospital (KKUH) in Riyadh, Kingdom of Saudi Arabia and subsequently had a histopathologic diagnosis of hepatic granulomas. Infections contributed to 56% and were represented mainly by schistosomiasis and to a lesser extent by tuberculosis, brucellosis and hydatid disease. Lymphomas (8%) were the major representative of noninfectious causes.

Seroepidemiology of hepatitis B virus infection in Saudi children 8 years after a mass hepatitis B vaccination programme.

Objectives: On October 1 1989, a programme was begun in Saudi Arabia in which the HBV vaccine was added as the 'seventh' primary immunogen of the Extended Programme of Immunization (EPI). In 1990, another programme was launched by the Ministry of Health to vaccinate all school children. Eight years after this mass vaccination programme, the efficacy of HBV vaccine was evaluated in a community-based study.
